午夜深藍上交錯的三色霓虹線

Digital painting for wallpaper use, strictly cropped to 16:9 with wide horizontal framing and even margins so it reads cleanly on desktop and TV screens. The field is deep midnight, dark navy, crossed on the diagonal by luminous strands: a single bright teal line sits in the left third, two magenta lines cross the centre-right, and a warm yellow accent weaves through the lower-right third, with the crossing point a little right of centre. The middle of the frame stays active with intersecting light, while generous negative space fills the upper-left two-thirds to balance it. Every line is a soft-edged glow with a crisp inner core and a smooth falloff into the navy, producing subtle bloom and a mid-tone haze. On the brightest contours, allow slight diffusion and painterly edge bleed, and add a faint bokeh of distant points in the upper-right quadrant. Depth is moderate: strands in the foreground are sharp, background strands softened to suggest layered distance.
